There are several important factors to consider when selecting fire sprinkler:
Type of hazard
What is being protected (office, warehouse, kitchen, etc.)? Different hazards require specific sprinkler responses.
Temperature rating
Sprinklers must open at the proper temperature for the hazard. Too cool and they may false alarm.
Size and layout of protected area
Ensure adequate coverage. Sprinkler spacing and position matters.
Water supply
Flow rates and pressure needs to match sprinkler demands for the space.
Applicable codes and standards
All sprinklers must meet requirements for intended use and jurisdiction.
Aesthetics
Concealed sprinklers are used to preserve appearances in finished areas.
Durability
Harsh or corrosive environments may require special coating or material.
Cost
More complex systems have higher upfront and maintenance costs. Balance with needs.
Existing piping
Retrofit projects may have limited pipe space for new sprinklers.
Proper selection based on these factors helps ensure sprinklers activate as intended in a fire to control its growth and spread quickly. Consider working with a fire protection engineer for design guidance.
